EDDO V. BATES, OF LOWELL, vMASSAGHUSEZIP'I."S, ASSIGNOR TO BATES 8t ROBINSON MACHINE COMPANY, OF LOWELL, MASSACHUSETTS, A (ZORPORA ''JIION.-

CABIDING-ENGINE.

To all whom it may concern Be 1t known that I, Eono V. BATES, a citizen of the United States, residing at Lowell,

inethe county of Middlesex and State of Massachusetts, have invented certain new sidered with reference to the top thereof and to the direction in which the stock was ing ends of the machine, have always pitched forward. Around such cylinder have been arranged one or more workers with teeth point to point with those on the main cylinder and one or more strippers which engaged the workers and had teeth back to point with those on the main cylin- .der.

The surface speed of some or all of the workers was very slow compared with that of the main cylinder, one result of which was a breaking and tearing of the stock between the verv fast roll and the very slow roll. Another result of this arrangementwas that to clear the workers, the strippers must run at a faster speed. and to clear the strippers, the main cylinder must runstill faster than the strippers. A further result of this arrangement was that'the stock was pulled in right into the teeth of the main cylinder and was with difiiculty cleared therefrom by'the fancy. doifer and comb.

I prefer to use a relatively large main cylinder because the angular relation of a large cylinder to the other rolls is smaller and the danger of breaking the stock is therefore reduced. lVith my arrangement of main cylinder,.there is practically no chance of uncarded stock being forced into the teeth and carried along to the doifer for the reason.

that the teeth of my main cylinder rake backward instead of forward and I run my main cylinder at a low rate of speed. In-

feet per minute more or less, I gear or rig my main cylinder to travel from ten to fifty feet per minute more or less. It will be readily understood that such a cylinder can be easily cleared by suitable rolls running at a relatively low speed, if desired.

I find it desirable to arrange strippers, in. such a manner that the stock on the main cylinder will be cleared off entirely one or more times, preferably two or three times, between the receiving side and the doffer. I can so arrange my delivery rolls that part of the stock will pass under and back with the main cylinder or so that it will all be cleared off. I arrange my rolls in such manner that there is no clogging of the main cylinder at any time and I prefer to arrange them in groups of substantially three or four principal rolls around the main cylinder.

In a card of my construction, the centrifugal force of the main cylinder is greatly reduced with the speed, whereby there is little throwing off of stock onto the floor, or other waste. The stock is mixed and blended much better as it all comes of! and goes on again several times. The mixing is so much better that I need no second breaker thereby saving a large amount of floor space and power. I also prefer to arrange my rolls which card so that the first rolls which receive the stock and card itshall have a comparatively low separating speed at the point of carding contact, whereby the stock .is

much less likely to be injured or broken. I

ranging the rolls so as to include the first worker of the tirst group of rolls; I prefer large strippers also as they can be run more slowly than small strippers and the'stock does not wind up on them.

My arrangement of rolls is, in general, in groups wherein the first toreceive the stock travels faster than the main cylinder but with relative slowness while the succeeding two or three principal rolls of each group travel faster. From the last and fastest roll, the stock is removed by means of a fancy and doffer and returnedto' the main cylinder, or it is taken off directly by similar means. In either event, it is carried along to the {slowest running roll group by the main cylinder. 1th each group, in proper relation, I prefer to use a slow running worker running at from ten to twenty feet surface speed per minute in connection with the other rolls which run at from .100 to 900 feet per minute. \Vith my arrangement. I expect with eight principal rolls. eight carding points, with nine principal rolls. nine carding points or in other words at least one carding point for .each

principal roll, and all the stock is reworked.

By principal rolls, I mean those rolls, exclusive of the main cylinder, which do not serve merely as feed rolls, bur rolls, fancies, transfer rolls or dolfers.

The principal featureof my invention is the main cylinderwith teeth which pitch backward instead of forward and which runs at a low speed instead of at a high speed together with one or more rolls in operative relation therewith for working the stock. More particularly, it is such a cylinder with one or more groups of rolls each group having one or more rolls. the rolls being so arranged that the main cylinder is stripped clear of stock at one or more points. Still more specifically, it is such a cylinder with such groups, wherein the rolls are smaller than the main cylinder one or more being in carding contact with the main cylinder and the other rolls being arranged for assisting such roll or for reworking the stock. Preferably each group comprises a plurality of principal rolls some of which run at successively higher speeds from the point of receiving to the point of delivering the stock, and preferably in connection with one or. more delivery rolls, for clearing the fastest roll of each group. Preferably also each group comprises a slow running worker which engages two of the other prin- -cipal rolls.

In the drawings, I show three types of cards with my invention in operation, but

it may be applied in various other ways which will naturally suggest themselves.

In the drawings, Figure 1 IS a diagrammatic side elevation of a card embodying my invention with the rolls arranged in .groups of substantially equal size. .such

groups being arranged around the main cylinder, and separated one from the other. Fig. 2 is a diagran'n natic side elevation of a card embodying my invention wherein the rolls are'arranged in groups of substantially equal size, such groups not being separated, however, but being so arranged that the last roll of one group engages the first roll of the next group. Fig. 3 is a diagrammatic side elevation of a card embodying my invention wherein the arrangement of rolls 'in the groups is somewhat modified and in which the number of rolls is reduced and of the next.

.also in which two groups are brought together by the elimination of other rolls.

In all the drawings. A represents the frame, B represents the main cylinder. 0

stated. has teeth which .pitch backward in stead of forward and travels at a low surface speed. v

In referring to the direction of travel of the various rolls, I will use the term forward when its top travels from left to right and backward when it travels from In speaklng of the teeth. I

right to left. will use the terms pitch forward or pitch backward The feed rolls and bur clipper F are of well known construction as is also the'licker-in G. This licker-in has teeth which pitch forward and travels forward at a speed of perhaps 100 feet per minute. In the construction shown in Fig. 1. 11 is a tumbler or tumbler worker which has teeth which pitch backward and which travels backward at a surface speed of perhaps 200 feet per minute, that is. faster than the licker-in. As the main cylinder 13 travels forward at a surface speed of perhaps 12 feet per minute, the stock 50 will be carded between its teeth and those on the first principal roll or tumbler worker 11. The stock 50 which is received from the feed rolls and licker-in is split at the above card- 51 and 52 are stripped and transferred to the second principal roll 12 which travelsat a higher rate of speed than 11, say 100 feet per minute. and has teeth which pitch forward and are in stripping relation with the teeth on B and 11. Between first roll 11 and second roll 12- is a third principal roll 13 which is essentially a worker having its teeth pitch forward and in carding'contact with 12 and in stripping contact with 11. It preferably travels backward and preferably at a low surface speed such as 12 feet per minute. It must travel more slowly than the roll1'2. It cards the stock. between itself and 12 and picks up part of the stock 53 from 12 and is stripped thereof by 11. 'lhis stock 53 merges with 50 and is recarded be tween llo and B. The rest of the stock which remains on 12 is brushed up by a a a faster speed than themain'cylinder as say 20 feet per minute. There-ice space between this group and the'next group,ofwhich the first roll 20, which corresponds with 11, has teeth which pitch backward, and runs backward at a similar s'pee i-':;t f1=h has teeth which pitch in the same ..di rection andtravels in the same direction at about teeth which pitch forward in the same way, and travels at about the same'relative speed. The "other members of the group are the fancv 23 which corresponds with 1% and the dofl'er 24 which-corresponds with 15." Thestock is blended and carded by this group in substantially the same way'as by the first group, being reworked and replaced on the main cylinder in the same manner There is space between this group and the third group which comprises the rolls 30, 31 and 32 which correspond in pitch of teeth, direction of travel and speed with 20, 21 and 22 and 11, 12 and 13. The fancy, which may be called the main fancy, -K corresponds with 23 and 14 but the main dofier H which corresponds with 2-1 and 15 is out of engagement with. the main cylinder whereby the stock S in- 4b are carding points between 11' and B, be-

. tween 12 and 13, -12 and 15, between, 20 and B, 21 and-22, and 21 and 24, also between 30 and B, 31 and 32, and 31- and H. This makes nine carding points with nine principal rolls.

In the construction shown in Fig. 2, the frame A, main cylinder B and the rolls C, D, E, R11 and Ktogether with comb L are the same and their speeds are the same'except that of-main cylinder B which I prefer should travel at about 30 feet surface speed per minute. The various speeds are substantially the same and the teeth of the various rolls in the various groups pitch in the same direction with those shown in Fig. 1, In the adjustment, however, the roll 15 is brought up into stripping contact with roll 2Q and roll 24 is brought into stripping contact with roll 30. The result of this and of making main cylinder'B travel at a surface speed faster than 15 or,2& isthatits teeth do not pick up the stock from those rolls, but merely brush by the stoclrwhich' is strippedby thefaster running rolls 20 and 30. Another. variation which I' show the same relative speed. The third 'roll 22 1s a worker which corresponds with 13, has

stead of'being'returned to the main cylinder clear of stock. In this construction, there .instead lof"stripping that part 56 of the stock Which in the carding between the maiii cylinder and. first roll 30 is left on the teeth i A second roll 21 which corresponds with 12- of the main cylnder, such stock 56'con merged with the stock 50 which is taken in by the feed rolls. 7 p In the construction shown in Fig. 3, the frame A, main cylinder B, rolls C, D, F, G, H and K together with-comb Lare thesameas in the other constructions with; teeth pitching in the same direction with those there shown. The main doifer H is shown as somewhat larger and,v the main cylinder B travels at perhaps 12 surface feet v The first principal roll 11 and the second and third principal rolls 12 and 8E: 13 of the first group are the same in pitch of teeth, direction of travel and speed as those in the other two constructions shown.

Instead of a doffer'such as 15. however, I

place a roll (30 which I will call the fourth principal roll, having teeth which pitch backward, in such position that it will be in stripping relation with second principal roll 12- and in carding relation with the main cylinder B. I also find it necessary or desirable to locate a fast running long toothed fancy 61 in such position'that itwill brush up the stock on the-roll 60 so that its teeth will not become filled up. This fourth principal roll should travel faster than 12 at perhaps 800 surface feet per minute. Part of the stock 57 after the carding between roll 60 and B remains on 60 as shown. Between this first-group of four principal rolls and the next group, I

prefer to leave a space. The next group :I have taken out fancy 23 and dofl' er 24 and have brought together the groups 20, 21, 22 and 30, 31, In so doing it be comes necessary to increase the speed of 30 so that-it will run faster than 21, as perhaps 100 feet per minute. By so doing, this roll which may be considered from one view point to be the fourth principal roll of the second series. replaces 24: as 60' replaces 15 and in each case such fourth roll instead of carding with the second roll, strips it and cards with the main cylinder. Boll 32 is the same as before and roll 31 in order to strip 30 is speeded up toperhaps 900 feet 80 or more spaces between various groups and n .cipal roll. 1

per minute. is preferably adjusted so as to be out of stripping contact with the main described. It willbe noted that whatI have called the fourth rolls of each group as 60 and 30 travel at a relatively fast speed coinpared with the slow running do ffers 15 and The result of this is that they card with the main cylinder and strip the second roll. A fancy is not necessary for roll 30 as it is witlrroll GO'because roll 30,.is thoroughly stripped by the fast running roll 31 whose teeth are kept clear by main doffer H.

,Tlie carding points in the construction shown in Fig. 2 are'the same as those shown in Fig. '1. that is nine or one for each prin- In the construction shown in Fig. 3, however. I have only eight carding 13, GO and B, and B, 21 and 22, and B, 31 and 31 and H. In this construction, I dispense with one doifer and one fancy and bring my rolls together more compaetly whereby asmaller main cylinder may be used, or with a larger main cylinder, other series or groups of rolls might be It..is anad iintage in setting to have one it is anadvantage with some kinds of stock to set the main doffer and the last roll of the last series away from the main cylinder so that foreign matter such as chives and dirt can drop to the floor. This last arrangement also permits a complete reworking of part of the stock and as the main cylinder travels slow there is little or none of the fiber thrown off onto the floor by centrifugal force as is the case with a fast running main cylinder.

It will be observed that with the successively-increasing speed of the rolls in each group and especially with. therelatively low speed of first roll or tumbler 11, the stock is more gently handled than between a slow running worker and a very fast main cylinder'as is the arrangement on ordinary cards. The result is much-less breaking of stock.

' prefer in connection with my main cylind'er to use groups of rolls which ivill not only card therewith but will card with each other whereby the stock will be worked, reworked and blended more completely and in a smaller space. than if single workers and strippers in pairs were used. Such an arrangement in pairs may be made if desired.

For replacing the stock on the main cylindergI find it desirable to use a long toothed fancy to brush up the stock on the doffer or roll which takes the place thereof unless, as in the construction shown in Fig. 3, two groiws are brought together in such a man.- ner that the last roll of the first group and 1 with tlielatter traveling enough faster than cylinder whereby the stock 56 travels un-. derneath with the main cylinder as before the first roll ofthe last group come together the former .to strip it. IVith such a con- -str'uction, the fancy and dofter between these 1 groups may be dispensed with and the fancy and dofi'er of the last group may do the work.

vThe construction shown in Fig.,3 combines many advantages as, for instai'i'ce, it is more compact at the same time that ,the

fastest rolls of each group can be operated within a reasonable limit of speed while the spacebetween the groups makes the rolls easier to set. This construction may be regarded as two groups, of four and six prin- 1.
